Abaphuhlisi kutsha nje ngasemva Isikhangeli sewebhu seGoogle Chrome sikhuphe iindaba zokongezwa kwenkxaso ye-HTTP / 3 protocol kulwakhiwo lweCanary Canary, Esebenzisa iplagi ukwenza i-HTTP ngaphezulu kwe-QUIC.
Umgaqo-nkqubo we-QUIC ngokwawo wongezwa kwisikhangeli kwiminyaka emihlanu edlulileyo Ukusukela ngoko isetyenziselwe ukwandisa umsebenzi kunye neenkonzo zikaGoogle. Kwangelo xesha, inguqulelo ye-QUIC kaGoogle esetyenziswe kwiChannel yahlukile kwezinye iinkcukacha ezivela kuhlobo lweenkcukacha ze-IETF, kodwa ngoku ukuphunyezwa kuyahambelana.
I-Google Chrome Canary yaba sisikhangeli sokuqala (esikhoyo) sokudibanisa (kakhulu) kuvavanyo #IQabane kunye ne-HTTP / 3 inkxaso!
Yongeza iiflegi "-i -able-quic -quic-version = h3-23" kwaye kuya kufuneka ubone "http / 2 + quic / 99" zibonakale kwii-devtools, eyi-http3 ngokufihlakeleyo! pic.twitter.com/5Fhui46h3x

Kubalulekile ukuqaqambisa oko UGoogle uphuhlise i-QUIC (Unxibelelwano olukhawulezayo lwe-UDP ye-Intanethi) ukusukela ngo-2013 njengenye indlela eya kwiphakheji ye-TCP + TLS yeWebhu, esombulula iingxaki ngoqwalaselo olude kunye namaxesha othethathethwano ngonxibelelwano lwe-TCP kunye nokususa ukulibaziseka kwilahleko yepakethi ngexesha lokudluliswa kwedatha.
I-QUIC yinkqubo ye-UDP exhasa ukuphindaphinda konxibelelwano oluninzi kwaye inikezela ngeendlela zokubhala ngokulingana ne-TLS / SSL.
Umgaqo-nkqubo ekuthethwa ngawo sele wakhiwe kulwakhiwo lwezixhobo zeGoogle, luyinxalenye yeChannel, icwangciselwe ukufakwa kwiFirefox, kwaye isetyenziselwa ukubonelela ngezicelo zabathengi kwiiseva zikaGoogle.
Phakathi kweempawu eziphambili ze-QUIC ezibalaseleyo zezi:
- Ukhuseleko oluphezulu, olufana ne-TLS (enyanisweni, i-QUIC ibonelela ngokwazi ukusebenzisa i-TLS ngaphezulu kwe-UDP)
- Ukuhamba kolawulo lokugcina ingqibelelo okuthintela ukulahleka kwepakethi
- Isakhono sokumisela unxibelelwano kwangoko (i-0-RTT, malunga ne-75% yamatyala, idatha inokuhanjiswa kwangoko emva kokuthumela ipakethi yokuseta uqhagamshelo) kunye nokuqinisekisa ukulibaziseka okuncinci phakathi kokuthumela isicelo kunye nokufumana impendulo (i-RTT, ixesha elijikelezayo lokuhamba)
- Ungasebenzisi inani elifanayo lokulandelelana xa uphinda uthumela ipakethi, ethintela ukungaqondakali ekumiseni iipakethi ezifunyenweyo kunye nokususa ixesha lokuphuma
- Ukuphulukana nepakethi kuchaphazela ukuhanjiswa komjelo kuphela onxulumene nawo kwaye akuyeki ukuhanjiswa kwedatha kwimilambo edluliselwe ngokudibeneyo kunxibelelwano lwangoku
- Izixhobo zokulungisa iimpazamo ezinciphisa ukulibaziseka ngenxa yokuhanjiswa kwakhona kweepakethi ezilahlekileyo.
- Ukusetyenziswa kweekhowudi zokulungisa iimpazamo zenqanaba elikhethekileyo ukunciphisa iimeko ezifuna ukuhanjiswa kwakhona kwedatha yepakethi elahlekileyo.
- Imida ye-cryptographic yeebhloko ilungelelaniswe nemida yeepakethi ze-QUIC, ukunciphisa isiphumo sokulahleka kwepakethi ekumisweni komxholo wezi pakethi zilandelayo
- Akukho ngxaki ekuthinteleni umgca we-TCP
- Inkxaso yesazisi sonxibelelwano, esinciphisa ixesha lokuseka ukunxibelelana kwakhona kwabaxhasi abahambahambayo
- Amandla okudibanisa iindlela eziphambili zokulawula umthwalo ongaphezulu koqhagamshelo
Kukwacacisiwe ukuba isebenzisa ubuchwephesha bokuqikelela ubungakanani bebhendi kwicala ngalinye Ukuqinisekisa ubungakanani obufanelekileyo bokuhanjiswa kwepakethi, ukuthintela ukuba kungafikeleli kwimeko yokuxinana apho ilahleko yepakethi ibonwa khona;
Njengo ukusebenza okumangalisayo kunye nokuzuza kokusebenza ngaphezulu kweTCP. Iinkonzo zevidiyo ezinje ngeYouTube, i-QUIC ibonise ukuncipha okungama-30% ekusebenzeni kwakhona xa ubukele iividiyo.
Umgaqo-nkqubo we-HTTP / 3 umisela ukusetyenziswa kwe-QUIC njengezothutho lwe-HTTP / 2. Ukwenza i-HTTP / 3 kunye ne-QUIC inguqulelo ye-23 yoyilo lwe-IETF, i-Chrome kufuneka iqhutywe kunye nokukhetha "-enable-quic -quic-version = h3-23" kwaye xa kuvulwa indawo yokuhlola i-quic .rocks: 4433 in imowudi yokuhlola inethiwekhi kwizixhobo zokuphucula, umsebenzi we-HTTP / 3 uza kubonisa njenge "http / 2 + quic / 99".
Xa kuthelekiswa nepakethi elahlekileyo ngonxibelelwano oluhambelanayo lwe-HTTP, lunye kuphela kunxibelelwano oluninzi oluya kuyekiswa, oko kuthetha ukuba i-QUIC inokuxhasa ukuhanjiswa kwe-oda ngaphandle ukuze ipakethi elahlekileyo ingabinampembelelo incinci.
Si ufuna ukwazi ngakumbi ngayo malunga noku, unokuqhagamshelana eli khonkco lilandelayo.
